Who called from 9175127782

Got a text at 3:08am with a activation code an then a phone call same thing , some kind of scam

Called again same thing at 3:27am with my four digit activation code

Received a phone call at 1:54 am with an activation code & thanking me for using their service. Never asked for any service!

Received the text with activation code first, then the first call within a minute from receiving the text at 6:00 am. Was confused so set the phone down and tried to go back to sleep. 10 Minutes later another call came in from same number followed by 2 more texts with activation code.

Received a call at 2am with an activation code for chess.  I never subscribed to any such service, and I'm supposed to be on the national do not call list.
